Understanding HTTP Status Codes

HTTP status codes are standardized response codes returned by web servers to indicate the result of a client's request. Monitoring these codes helps website owners troubleshoot issues, ensure proper functioning, and optimize for search engines.

Main Categories of HTTP Status Codes

2xx - Success

  • 200 OK: The request was successful
  • 201 Created: The request succeeded and a new resource was created
  • 204 No Content: The server successfully processed the request but isn't returning any content

3xx - Redirection

  • 301 Moved Permanently: The resource has permanently moved to a new URL
  • 302 Found: The resource temporarily resides under a different URL
  • 304 Not Modified: The resource hasn't been modified since last requested

4xx - Client Errors

  • 400 Bad Request: The server cannot process the request due to a client error
  • 403 Forbidden: The client does not have permission to access the resource
  • 404 Not Found: The requested resource could not be found
  • 429 Too Many Requests: The user has sent too many requests in a given time

5xx - Server Errors

  • 500 Internal Server Error: A generic error occurred on the server
  • 502 Bad Gateway: The server received an invalid response from an upstream server
  • 503 Service Unavailable: The server is currently unavailable (overloaded or down for maintenance)
  • 504 Gateway Timeout: The upstream server failed to send a request in the time allowed

Why Monitoring Status Codes Matters

  • SEO Impact: Search engines pay attention to HTTP status codes. 404s and 500s can negatively affect your rankings.
  • User Experience: Broken pages and server errors lead to poor user experience and higher bounce rates.
  • Resource Management: Identifying and fixing problematic URLs helps optimize crawl budget and server resources.
  • Security Monitoring: Unusual status code patterns might indicate security issues or attack attempts.
